Robert;
The catalog I was quoting from is the Adolf frank Export catalog known as "Alfa" dated 1911, a gun digest reprint. I did a little further looking & discovered I had skipped another page containg 3 models of FNs. All seem to be the same design & are stated to be quadruple bolted, though I see only the double underbolts & a crossbolt, don't know what they are calling the 4th one. All do have side clips & are extractor guns. first one is unengraved @ 156 Mark, next has "Arabesque" engraving @ 204 mark & the last has "Artistic Dragon" engraving @ 228 Mark. All available in 12 or 16 ga. In "This" catalog the only bbl steel mentioned on the FNs is Coquerill. According to an exchange table in front of catalog, subject to slight fluctuations, the 1911 US Dollar was equal to 4,20 Marks (4 Reichsmark, 20 pfennig). I am certain this was not the entire FN line of the day, but only what Alfa listed. One would certainly think they would have offered engraved versions of thier ejector model as well as the extractor gun.
